To all whom it concerm.

Be it known thatI, WILLIAM L. jKonnie, a

tion.

In bar rooms and other places where liquid refreshments are dispensed,usually behind the bar'or at some place conveniently at hand a tank ortub water for rinsing the glasses used. The tub is commonly suppliedwith flowing water and the water is maintained at av particular levelstanding in the tub, and having its outlet through a by means of anover-flow pipe suitable opening in the bottom of the tub. This over-flowpipe usually discharges into a 'waste pipe that leads to a sewer, andthe and has his health endangered gases and odors arising from suchover-flow ipe. ,Y

The object of this invention, therefore, is, among others, to provide animproved overflow device in which these foul gases are prevented fromescapin into the room.

A further object o the invention is to provide means whereby of water inthe tank within limits as desired.

such a way that they can each therefore readily cleaned.

The invention is embodied in the conand then pointed out in the claims.

In the accompanying with my improved Fig.

and with the adjustable sleeve for .adjusting the level of the outletdrawn down... Fig. 3 is asimilar view with the sleeve pushed up. Fig. 4is a sectional view of the trap detached.

In the views the character 6 designates the tub. The ltub is shown asprovided in its bottom with an Ordinar waste or discharge opening, saidopening, eing provided with a suitable seat for the reception of theoverflow pipe.

7 designates the over-iiow pipe which is and State certain new4 andthere is to contain -its upper refreshments is much annoyedv by the foul'such depth that when the height of the level canbe varied and fixed 'Afurther object is to contrive the parts in be separated and structionvhereinafter particularly set forth drawings-Figure 1 is a verticallongitudinal sectional view of i 2 is an elevation of the, outlet pipewith the trap thereon in section;

at ItL to removably but fluid-tightly fit in the seat provided for it inthevbottom of the tub. The overflow pipe 7 is'provided near its upperend with a series of holes or slots 7b constituting ports through whichthe water overflows from the tub into the pipe.

8 designates a sleeve that is made to closely but to vbe capable ofbeing readily slid up yor down on the pipe and of remaining by frictionat the place to which it is slid. When the sleeve is slid lup beyond thelower ends of the ports the upper edge of the sleeve and not the lowerends of the ports x the level at which the water shall. stand in thetub, and this level, by raising or lowering the sleeve between theextremities of the slots, can be changed as desired.

9 designates the trap. This trap is in the form of a conical'petticoat.It is closed at end and formed with asocket as seen at 9t1 to fit snuglyon the upper end of the overflow pipe. The petticoat is made of fittedin place Von the overflow -pipe the margin or lower edge of its skirt issubmerged at all times in the subjacent waters The overflow at presentin common use in'tubs of the character herein referred to is merely apipe open at its upper end, and bar keepers are oftentimes compelled toresort to the expedient of temporarily plugging or corking 4up the endof the pipe to stop the stench from filling the room. I But in such casethe flow of fresh water to the tub must be cut olf, otherwise the placewould be flooded. When not constantly renewed the water soon becomesstale and unfit for rinsing purposes. With my invention sewer gas orfoul odors are kept bac and prevented from entering the room. The watercan be supplied to the tub in a constant flow, and, therefore, kept cooland clean. The advantage-of adjusting the level of the water in the tubaccrues from the fact that tumblers or glasses are oftentimes ofdiferent height. The depth of water convenient. for rinsing thei'n can,therefore, be varied without materially affecting the eiliciency of thetrap.

What I claim and desire to secure by Letters Patent is:

l. In combinationl with a rinse tub,'an overflow pipe therefor havingits upper portion provided with a port below the upper end'thereof, aslidable sleeve on said pipe to raise or lower the level of the inletkes through said port to said pipe, and a pettil coat trap on the upperend of said pipe.

2. In combination with a rinse tub, an" overliow pipe having itsuppervporton pro-- vided with a'port extending longitudinally ofthepipe, a slidable sleeve on said pipe to raise or lower the level oftheinlet through said port to said pipe, and a petticoat trap on the upperend of said pipe.
